Characterizing Vortex-Driven Dynamics in the Solar Atmosphere Using Information Theory
Suzana S. A. Silva, Erico Rempel, Gary Verth +2
Solar vortex regions show enhanced Poynting flux and favourable heating conditions, but how the vortices reorganize and influence their surroundings remains unclear. Here we apply…
Alfven Waves in Partially Ionised Solar Steady-State Plasmas
Nada F. Alshehri, Istvan Ballai, Viktor Fedun +1
Our study investigates the properties of Alfvén waves in partially ionised solar plasmas in the presence of steady, field-aligned, flows of charged and neutral particles. Our work…
Solar Vortices as Conduits for Magnetoacoustic Waves: Multi-Layer Coupling and Their Role in Atmospheric Heating
Suzana S. A. Silva, Ioannis Dakanalis, Luiz A. C. A. Schiavo +10
The Sun's atmosphere hosts swirling plasma structures, known as solar vortices, which have long been thought to channel wave energy into higher layers. Until now, no direct observa…
Global CME-driven oscillations in the outer solar corona
Suzana S. A. Silva, J. J. Gonzalez-Aviles, Pete Riley +8
Coronal mass ejections (CMEs) are known drivers of large-scale waves in the low corona. However, wave dynamics in the extended corona and inner heliosphere remain largely unexplore…
Driven phase-mixed Alfvén waves in a partially ionized solar plasma
Max McMurdo, Istvan Ballai, Gary Verth +1
Phase mixing has long been understood to be a viable mechanism for expediting the dissipation of Alfvén wave energy resulting in the subsequent heating of the solar atmosphere. To…
3D MHD wave propagation and energy transport in a simulated solar vortex
Samuel Skirvin, Viktor Fedun, Gary Verth +1
Magnetic flux tubes in the presence of background rotational flows are abundant throughout the solar atmosphere and may act as conduits for MHD waves to transport energy throughout…
